Frunzеnsky mall, Regional heritage commercial building on Moskovsky Prospekt, Saint Petersburg, Russia.

The Frunzensky mall stands at the corner of Moskovsky Prospekt and the Obvodny Canal, built 1934–1938 by architects Yevgeny and Leonty Katonin, Yevgeny Sokolov and K. Ioganson. It joins a massive rectangular corner block to a long, slightly convex wing that follows the canal's bend. Its facade of paired columns wraps around the turn, and the sales halls' outer wall carries four storeys of simplified Doric columns with glazing between them. Since 2015 the interior holds offices.

Built between 1934 and 1938 to designs by Yevgeny and Leonty Katonin, Yevgeny Sokolov and K. Ioganson, the building opened as a department store in 1938. Bombing damaged it in 1942, yet it was restored and reopened in summer 1944. A 1988 fire destroyed much of the interior; after partial reconstruction it served as a mall until 2007, then was rebuilt inside and reopened in September 2015 as offices.

The name comes from Mikhail Frunze, a Soviet military commander; the building opened as a department store in 1938. Since September 2015 it has housed offices, and from Moskovsky Prospekt the city government's "single window for investors" operates here. The facade was restored with the dark grey terrazzo plaster used in the 1930s.

The building stands at the corner of Moskovsky Prospekt and the Obvodny Canal, with the main entrance to the former sales halls on the prospekt side. Since the 2015 conversion it houses offices and the city government's single-window service for investors, so visitors come for administrative business rather than shopping. A car park beside the building, created after the neighbouring house No. 58 was demolished, was unusual for a retail site in the historic centre.

The dark grey terrazzo render of the 1938 facade was reapplied during the 2014 renovation with input from St Petersburg's state restorers. Since September 2015 the building has housed rentable offices, and a 'single window for investors' of the city government opened on the Moskovsky Prospekt side.
